This text provides comprehensive coverage of parallel algorithms and architectures, beginning with fundamental concepts and continuing through architectural variations and aspects of implementation. Unlike the authors of similar texts, Professor Parhami reviews the circuit model and problem driven parallel machines, variants of mesh architectures, and composite and hierarchical systems, among other subjects. With its treatment of theory and practical designs, class tested lecture material and problems, and case studies, the book is suited to graduate and upper level undergraduate students of advanced architecture or parallel processing.
